Substitute Part Grouping Explanation

Substitute parts are classified into two primary categories based on electrical and mechanical compatibility with the 104693-2:

Category 1: Direct Equivalent (TE Connectivity) The part 5-104693-2 maintains identical electrical specifications, mechanical dimensions, and connector geometry. This substitute differs only in RoHS compliance status (ROHS3 Compliant versus RoHS non-compliant) and contact finish post material (Tin versus Tin-Lead). This part is selected when regulatory compliance with RoHS3 requirements is mandated while maintaining the original TE Connectivity manufacturing source.

Engineering Selection Recommendations

For RoHS3 Compliance Requirement with Identical Performance: Select part 5-104693-2 when regulatory compliance with RoHS3 standards is required while maintaining identical electrical specifications and mechanical compatibility with the original 104693-2. This part is manufactured by TE Connectivity and maintains the same AMPMODU 50/50 Grid series designation. The only functional difference is the contact finish post material (Tin versus Tin-Lead), which does not affect mating performance.

For Enhanced Thermal and Current Performance: Select Samtec Tiger Eye™ TFM series parts (TFM-110-22-L-D-A, TFM-110-22-L-D-LC, TFM-110-22-S-D-A, TFM-110-22-S-D-A-P-TR, TFM-110-22-S-D-K-TR, TFM-110-22-S-D-LC) when applications require increased current capacity (2.9A per Contact versus 0.5A per Contact) and extended operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C). All Samtec substitutes maintain ROHS3 compliance and identical core connector geometry.

For Automated Assembly Processes: Select TFM-110-22-S-D-A-P-TR or TFM-110-22-S-D-K-TR when tape and reel packaging is required for pick-and-place assembly operations. Both parts include pick-and-place features and are supplied in Tape & Reel format with 2000 and 1309 units in inventory respectively.

For Board Locking Feature Requirement: Select TFM-110-22-L-D-LC or TFM-110-22-S-D-LC when board lock features are specified in design requirements. These Samtec parts provide board lock functionality equivalent to the original 104693-2 board lock feature.

For Board Guide Feature Requirement: Select TFM-110-22-L-D-A, TFM-110-22-S-D-A, or TFM-110-22-S-D-A-P-TR when board guide features are required. These parts provide board guide functionality as an alternative to the board lock configuration.

All substitute parts maintain active product status and are available in current inventory quantities ranging from 919 to 2000 units.

Frequently Asked Questions (FAQ)

Q: Can the 5-104693-2 be used as a direct replacement for the 104693-2 in all applications?

A: Yes. The 5-104693-2 maintains identical electrical specifications, mechanical dimensions, and connector geometry. The primary difference is RoHS3 compliance status. The contact finish post material differs (Tin versus Tin-Lead), but this does not affect mating performance or electrical characteristics. Selection depends on regulatory compliance requirements for your application.

Q: What are the key differences between the TE Connectivity 104693-2 and Samtec TFM-110 series substitutes?

A: The primary differences are current rating (0.5A versus 2.9A per contact), operating temperature range (-65°C ~ 105°C versus -55°C ~ 125°C), contact shape (circular versus square), contact length (0.120" versus 0.139"), and voltage rating specification (not specified versus 275VAC). All other core parameters including pitch, position count, mounting type, shrouding, fastening, and termination remain identical.

Q: Are Samtec TFM-110 series parts backward compatible with the 104693-2?

A: Samtec TFM-110 series parts are functionally compatible for board-to-board mating applications due to identical pitch (1.27mm), position count (20), and shrouded 4-wall configuration. However, the increased contact length (0.139" versus 0.120") and different insulation height (0.360" versus 0.367") may affect mating stack height and PCB layout. Verify mechanical fit in your specific application before implementation.

Q: Which substitute part should I select for high-current applications?

A: Select any Samtec TFM-110 series part (TFM-110-22-L-D-A, TFM-110-22-L-D-LC, TFM-110-22-S-D-A, TFM-110-22-S-D-A-P-TR, TFM-110-22-S-D-K-TR, or TFM-110-22-S-D-LC) for applications requiring current capacity greater than 0.5A per contact. These parts provide 2.9A per contact rating with 275VAC voltage specification.

Q: What packaging options are available for automated assembly?

A: Tape & Reel packaging is available for TFM-110-22-S-D-A-P-TR (2000 units in inventory) and TFM-110-22-S-D-K-TR (1309 units in inventory). Both include pick-and-place features. Tube packaging is available for all other substitute parts.

Q: Does the contact shape difference (circular versus square) affect electrical performance?

A: Contact shape does not affect electrical performance. The circular contacts in the 104693-2 and 5-104693-2 provide equivalent electrical characteristics to the square contacts in Samtec TFM-110 series parts. Contact shape is a mechanical design feature that does not impact signal integrity or current carrying capacity within the specified ratings.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5-104693-2 and all Samtec TFM-110 series parts are ROHS3 compliant. The original 104693-2 is RoHS non-compliant. Select compliant alternatives when regulatory requirements mandate RoHS3 compliance.

Q: What is the difference between TFM-110-22-S-D-A and TFM-110-22-S-D-LC?

A: Both parts are identical except for the fastening feature. TFM-110-22-S-D-A includes a board guide feature, while TFM-110-22-S-D-LC includes a board lock feature. Select based on your mechanical design requirement for connector retention.

Q: Can I mix and match substitute parts in the same application?

A: Yes, all substitute parts maintain identical core electrical and mechanical parameters (pitch, position count, mounting type, shrouding, fastening, and termination). However, verify that any differences in contact length, insulation height, or current rating do not conflict with your specific PCB layout and application requirements.

Q: What inventory quantities are available for each substitute part?

A: Inventory quantities are as follows: 5-104693-2 (1900 units), TFM-110-22-L-D-A (919 units), TFM-110-22-L-D-LC (956 units), TFM-110-22-S-D-A (1021 units), TFM-110-22-S-D-A-P-TR (2000 units), TFM-110-22-S-D-K-TR (1309 units), and TFM-110-22-S-D-LC (1017 units).
