Substitute Part Grouping Explanation

Substitute parts for the 104693-3 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Manufacturer): The part 5-104693-3 from TE Connectivity AMP Connectors is a direct equivalent. This substitute maintains identical specifications across all critical parameters: 30 positions, 2 rows, 0.050" (1.27mm) pitch, surface mount configuration, shrouded 4-wall design, push-pull fastening, and solder termination. The only variation is in the contact finish post material (Tin versus Tin-Lead) and RoHS compliance status (ROHS3 Compliant versus RoHS Compliant).

Cross-Manufacturer Alternatives (Samtec Inc.): The Samtec Tiger Eye™ TFM series connectors (TFM-115-22-L-D-A, TFM-115-22-S-D-A, TFM-115-22-S-D-A-K-TR, TFM-115-22-S-D-A-P-TR, and TFM-115-22-S-D-LC) are functionally equivalent based on the following matching parameters:

30 positions in 2-row configuration
0.050" (1.27mm) mating pitch
0.050" (1.27mm) row spacing
Surface mount solder termination
Shrouded 4-wall design
Push-pull fastening
Male pin contact type
Phosphor bronze contact material
Liquid crystal polymer insulation
UL94 V-0 flammability rating
MSL 1 (Unlimited) moisture sensitivity

Substitution differences are limited to contact shape (square versus circular), contact length specifications, insulation height, current rating capacity (2.9A versus 0.5A per contact), operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C), voltage rating (275VAC), packaging format (tube, cut tape, or tape & reel), and fastening feature variations (board guide versus board lock).

Engineering Selection Recommendations

Direct Equivalent Selection: The 5-104693-3 from TE Connectivity is the primary direct equivalent for the 104693-3. Both parts maintain identical electrical and mechanical specifications with active product status. Selection of 5-104693-3 is appropriate when maintaining the same manufacturer series (AMPMODU 50/50 Grid) is required or when existing design documentation specifies TE Connectivity components. The higher inventory availability (2221 pcs) of 5-104693-3 supports supply chain continuity.

Cross-Manufacturer Samtec Alternatives: The Samtec Tiger Eye™ TFM series connectors are functionally equivalent alternatives when cross-manufacturer substitution is acceptable. These parts satisfy all critical electrical and mechanical parameters: identical position count, pitch spacing, surface mount configuration, and solder termination. All Samtec alternatives maintain ROHS3 compliance and UL94 V-0 flammability rating.

Selection among Samtec alternatives depends on packaging and assembly requirements:

TFM-115-22-L-D-A (Tube): Standard tube packaging for manual assembly or low-volume production
TFM-115-22-S-D-A (Tube): Tube packaging with standard gold finish thickness
TFM-115-22-S-D-A-K-TR (Cut Tape): Cut tape format with pick-and-place compatibility for automated assembly
TFM-115-22-S-D-A-P-TR (Tape & Reel): Tape and reel format optimized for high-volume automated production
TFM-115-22-S-D-LC (Tube): Tube packaging with board lock fastening feature

Compliance Considerations: All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level, ensuring compliance with automotive, medical, military, and telecommunications application requirements. ROHS3 compliance of Samtec alternatives aligns with current regulatory standards.

Performance Differences: Samtec alternatives provide higher current rating capacity (2.9A per contact versus 0.5A per contact) and extended operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C). These enhanced specifications support applications with higher power requirements or broader thermal operating conditions. Contact shape variation (square versus circular) does not affect electrical performance but may influence mechanical fit in existing receptacle designs.

Frequently Asked Questions (FAQ)

Q: Can the 5-104693-3 be used as a direct replacement for the 104693-3?

A: Yes. The 5-104693-3 is a direct equivalent with identical electrical and mechanical specifications. Both parts feature 30 positions, 0.050" (1.27mm) pitch, surface mount solder termination, shrouded 4-wall design, and push-pull fastening. The primary difference is RoHS compliance status (ROHS3 versus RoHS Compliant) and contact finish post material (Tin versus Tin-Lead).

Q: Are Samtec Tiger Eye™ TFM series connectors compatible with the 104693-3?

A: Samtec TFM-115-22 series connectors are functionally equivalent based on matching electrical and mechanical parameters: 30 positions, 2 rows, 0.050" (1.27mm) pitch, surface mount configuration, and solder termination. Compatibility depends on receptacle design acceptance of square contact geometry (Samtec) versus circular contact geometry (TE Connectivity). Samtec alternatives provide higher current capacity (2.9A versus 0.5A per contact) and extended operating temperature range.

Q: What is the difference between the various Samtec packaging options?

A: Samtec alternatives are available in three packaging formats: Tube (TFM-115-22-L-D-A, TFM-115-22-S-D-A, TFM-115-22-S-D-LC) for manual or low-volume assembly; Cut Tape (TFM-115-22-S-D-A-K-TR) for pick-and-place automated assembly; and Tape & Reel (TFM-115-22-S-D-A-P-TR) for high-volume production lines. Electrical and mechanical specifications remain identical across all packaging formats.

Q: Do the Samtec alternatives have the same fastening features as the 104693-3?

A: All Samtec alternatives feature push-pull fastening. The primary fastening feature difference is board lock (TFM-115-22-S-D-LC) versus board guide (other TFM-115-22 variants). The 104693-3 includes board lock feature. The TFM-115-22-S-D-LC variant matches this board lock specification.

Q: What are the key electrical differences between the 104693-3 and Samtec alternatives?

A: The 104693-3 is rated for 0.5A per contact with operating temperature range -65°C ~ 105°C. Samtec TFM-115-22 series connectors are rated for 2.9A per contact with operating temperature range -55°C ~ 125°C and 275VAC voltage rating. These enhanced specifications support higher power applications and broader thermal operating conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 104693-3 is RoHS Compliant. The 5-104693-3 and all Samtec alternatives are ROHS3 Compliant, which represents current regulatory compliance standards. Both compliance levels are acceptable for automotive, medical, military, and telecommunications applications.

Q: What is the moisture sensitivity level for all these connectors?

A: All parts listed maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can I use the Samtec TFM-115-22-S-D-A-K-TR for automated pick-and-place assembly?

A: Yes. The TFM-115-22-S-D-A-K-TR is specifically formatted in cut tape with pick-and-place compatibility features. This variant is optimized for automated assembly processes and maintains all electrical and mechanical specifications of the base TFM-115-22 series.
