Parameter Comparison

Engineering Selection Recommendations

MA35-28P-2DS(51) is the direct substitute for MA35-28P-2DS(71). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: MA35-28P-2DS(71) is obsolete, while MA35-28P-2DS(51) is active and carries RoHS compliance certification. Selection of MA35-28P-2DS(51) ensures long-term availability and regulatory compliance for new designs or production continuity.

Frequently Asked Questions (FAQ)

Q: Can MA35-28P-2DS(51) be used as a direct replacement for MA35-28P-2DS(71)?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including pitch, row spacing, contact configuration, current rating, voltage rating, and operating temperature range. The substitute part is active and RoHS compliant.

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

A: The suffix designation (71) versus (51) indicates packaging and product lifecycle status. MA35-28P-2DS(71) is obsolete, while MA35-28P-2DS(51) is active with bulk packaging and RoHS compliance.

Q: Are there any compatibility concerns when switching from MA35-28P-2DS(71) to MA35-28P-2DS(51)?

A: No compatibility concerns exist. Identical mating pitch (0.079"), row spacing (0.079"), contact geometry, and termination method ensure direct interchangeability in PCB layouts and mating connector applications.

Q: What is the moisture sensitivity level difference?

A: MA35-28P-2DS(71) lists MSL as not applicable, while MA35-28P-2DS(51) is rated MSL 1 (unlimited). This indicates MA35-28P-2DS(51) has no moisture sensitivity restrictions for storage and handling.

Q: Is RoHS compliance a factor in selecting the substitute?

A: RoHS compliance is specified for MA35-28P-2DS(51) but not documented for MA35-28P-2DS(71). For applications requiring regulatory compliance, MA35-28P-2DS(51) is the appropriate selection.
