Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMM-110-02-FM-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (20)
• Pitch and row spacing (0.079" / 2.00mm)
• Mounting type (Surface Mount)
• Fastening mechanism (Push-Pull)
• Current and voltage ratings (3.2A per Contact, 350VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (UL94 V-0, ROHS3 Compliant)

The substitute part SMM-110-02-F-D meets all these criteria and belongs to the same Tiger Eye™ SMM series, ensuring mechanical and electrical interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the SMM-110-02-FM-D and SMM-110-02-F-D are active production parts with full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts should be based on inventory availability and supply chain requirements. The SMM-110-02-F-D currently has higher stock levels (863 units versus 763 units), which may support extended lead time requirements. Both parts carry identical electrical ratings, mechanical specifications, and environmental certifications, ensuring functional equivalence in applications requiring 20-position, 2.00mm pitch surface mount receptacle connectors with push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can SMM-110-02-F-D be used as a direct replacement for SMM-110-02-FM-D?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including connector type, position count, pitch, mounting method, fastening type, current and voltage ratings, and operating temperature range.

Q: What is the difference between these two part numbers?

A: The parts are functionally identical. The difference in part number designation reflects internal Samtec product line categorization but does not affect electrical or mechanical performance in applications requiring the specified parameters.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts use identical contact materials (Beryllium Copper), contact finishes (Gold), insulation materials (LCP), and mechanical dimensions. PCB footprints and mating interface specifications are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMM-110-02-FM-D and SMM-110-02-F-D are ROHS3 compliant, carry UL94 V-0 material certification, and have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain lead times. Both parts are active production items suitable for new designs. The SMM-110-02-F-D currently has higher stock availability.
