Substitute Part Grouping Explanation

The TMM-102-04-T-D-SM qualifies as a direct substitute for the TMM-102-04-TM-D-SM based on the following critical parameters that determine functional interchangeability:

• Identical pitch spacing: 0.079" (2.00mm) mating pitch and row spacing
• Identical position count and row configuration: 4 positions in 2 rows
• Identical mounting technology: Surface mount solder termination
• Identical electrical rating: 3.2A per contact
• Identical operating temperature range: -55°C ~ 105°C
• Identical material specifications: Phosphor bronze contacts with tin finish, LCP insulation
• Identical compliance certifications: ROHS3 compliant, UL94 V-0 flammability rating
• Identical moisture sensitivity level: MSL 1 (Unlimited)

Both parts belong to the TMM series and share the same base product number (TMM-102), confirming their functional equivalence for board-to-board and cable interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-102-04-TM-D-SM and TMM-102-04-T-D-SM are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The parts are functionally equivalent across all specified electrical and mechanical parameters. Selection between these parts may be based on inventory availability, lead time, or procurement preference, as no technical differentiation exists between them. The TMM-102-04-T-D-SM currently maintains higher inventory levels (1651 pcs vs. 1005 pcs), which may influence sourcing decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can TMM-102-04-T-D-SM be used as a direct replacement for TMM-102-04-TM-D-SM?

A: Yes. Both parts share identical electrical ratings (3.2A per contact), mechanical dimensions (4-position, 2-row, 0.079" pitch), mounting technology (surface mount solder), operating temperature range (-55°C ~ 105°C), and material specifications (phosphor bronze contacts, LCP insulation). They are functionally interchangeable.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level.

Q: What determines whether a part can substitute for the TMM-102-04-TM-D-SM?

A: Substitution is determined by matching the following critical parameters: mating pitch (0.079"), position count (4), row configuration (2 rows), row spacing (0.079"), mounting type (surface mount), termination method (solder), current rating (3.2A per contact), operating temperature range (-55°C ~ 105°C), contact material (phosphor bronze), and insulation material (LCP).

Q: Are there any package or handling differences between these parts?

A: Both parts are supplied in bulk packaging with identical moisture sensitivity level (MSL 1). No special handling differences apply between the two part numbers.
