Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF13EA-30DP-1.25V(21) is determined by strict equivalence across the following critical parameters:

• Connector geometry: 30 positions, 2 rows, 1.25mm pitch (mating and row spacing)
• Electrical specifications: 1A current rating, 150V voltage rating
• Mechanical interface: Surface mount termination, shrouded 4-wall design, male pin contact type
• Environmental compliance: UL94 V-0 flammability rating, operating temperature range -35°C to 85°C
• Material standards: Polyamide (PA) nylon insulation, brass contact material with tin-copper finish

The DF13EA-30DP-1.25V(22) qualifies as a direct substitute based on identical compliance with all critical parameters listed above. Differences in fastening type (Push-Pull versus Detent Lock) and contact finish specifications do not affect functional interchangeability within the defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The DF13EA-30DP-1.25V(22) is the direct active equivalent for the obsolete DF13EA-30DP-1.25V(21). Selection of the substitute part is based on:

• Product status alignment: The substitute is active and currently manufactured, ensuring long-term supply availability
• Regulatory compliance: Both parts meet UL94 V-0 flammability requirements and RoHS standards (the substitute carries ROHS3 certification, representing current compliance status)
• Electrical and mechanical equivalence: Identical pitch, position count, current and voltage ratings, operating temperature range, and contact material specifications
• Packaging consideration: The substitute is supplied in Tape & Reel format, which is standard for production environments and offers cost efficiency for volume applications

The change in fastening mechanism from Push-Pull to Detent Lock and the contact finish specification difference (Tin-Copper to Tin) do not impact functional interchangeability within the defined electrical and mechanical parameters of this connector category.

Frequently Asked Questions (FAQ)

Q: Can the DF13EA-30DP-1.25V(22) be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical electrical ratings (1A, 150V), mechanical dimensions (30 positions, 1.25mm pitch, 2 rows), mounting method (surface mount solder termination), and environmental specifications (-35°C to 85°C operating range, UL94 V-0). PCB footprints and mating interface requirements remain unchanged.

Q: What is the difference between Push-Pull and Detent Lock fastening types?

A: Push-Pull fastening uses a simple push mechanism for mating and pulling for unmating. Detent Lock employs a locking mechanism that requires deliberate action to release the connection. Both provide secure mating; the selection depends on application requirements for connection security and ease of service access.

Q: Does the contact finish change from Tin-Copper to Tin affect performance?

A: No. Both finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating parameters. Tin finish is standard for modern connector manufacturing and meets all RoHS and environmental requirements.

Q: Why is the substitute supplied in Tape & Reel packaging?

A: Tape & Reel is the standard packaging format for surface mount components in production environments. It enables automated assembly processes and provides cost efficiency for volume manufacturing. Bulk packaging is available through alternative channels if required for specific applications.

Q: Are there any design modifications required when switching from the obsolete to the active part?

A: No design modifications are required. The substitute maintains full mechanical and electrical compatibility with existing PCB layouts, mating connectors, and system interfaces.
