Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STMM-115-02-TM-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (30)
• Number of rows (2)
• Pitch - mating (0.079" / 2.00mm)
• Row spacing - mating (0.079" / 2.00mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Current rating (3A)
• Operating temperature range (-55°C ~ 105°C)
• RoHS compliance status (ROHS3 Compliant)
• Moisture sensitivity level (1 - Unlimited)

The substitute part STMM-115-02-T-D maintains all these parameters identically, differing only in the fastening mechanism designation within the part number suffix, which does not alter the core electrical or mechanical compatibility of the connector.

Parameter Comparison

Engineering Selection Recommendations

Both the STMM-115-02-TM-D and STMM-115-02-T-D are active production parts from Samtec Inc. with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and lead time requirements. The STMM-115-02-T-D currently has higher inventory (1049 units versus 1006 units), which may provide supply chain advantages. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating and are suitable for the full operating temperature range of -55°C to 105°C. Compliance certifications including ROHS3 status and EAR99 export classification are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can STMM-115-02-T-D be used as a direct replacement for STMM-115-02-TM-D?

A: Yes. Both parts maintain identical electrical and mechanical parameters including connector type, contact configuration, pitch, row spacing, mounting method, termination type, fastening mechanism, current rating, and operating temperature range.
