Substitute Part Grouping Explanation

The DF11-32DS-2DSA(06) qualifies as a direct substitute based on matching electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Identical connector type (Receptacle)
Identical number of positions (32)
Identical pitch spacing (0.079" / 2.00mm)
Identical row configuration (2 rows at 0.079" spacing)
Identical mounting method (Through Hole)
Identical termination options (Press-Fit, Solder)
Identical mating contact finish (Gold)
Identical current and voltage ratings (2A, 250V)
Identical operating temperature range (-30°C ~ 85°C)
Identical flammability rating (UL94 V-0)

The substitute part maintains full compatibility with applications designed for the original DF11-32DS-2DSA(01) connector.

Engineering Selection Recommendations

The DF11-32DS-2DSA(06) is the direct substitute for the obsolete DF11-32DS-2DSA(01). All critical electrical and mechanical parameters are identical, ensuring functional compatibility in existing applications. The substitute part offers two significant advantages: active product status with confirmed availability and ROHS3 compliance, compared to the non-compliant status of the original part. The post contact finish differs (tin versus nickel) with increased thickness in the substitute, which does not affect mating performance or electrical characteristics. Selection of the DF11-32DS-2DSA(06) is appropriate for new designs and replacement applications requiring the DF11 series 32-position receptacle connector.

Frequently Asked Questions (FAQ)

Q: Can DF11-32DS-2DSA(06) be used as a direct replacement for DF11-32DS-2DSA(01)?

A: Yes. All mating pitch, position count, electrical ratings, and mechanical dimensions are identical. The connectors are fully interchangeable in applications designed for the original part.

Q: What is the difference between the post contact finishes?

A: The original part uses nickel plating (39.4µin thickness) on the post contacts, while the substitute uses tin plating (78.7µin thickness). Both finishes provide adequate electrical conductivity and corrosion resistance for the specified operating conditions. The thicker tin finish in the substitute may offer improved durability in certain environments.

Q: Why is the original part listed as obsolete?

A: The DF11-32DS-2DSA(01) has been superseded by the DF11-32DS-2DSA(06), which maintains identical specifications while offering improved compliance and availability.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The DF11-32DS-2DSA(06) is ROHS3 compliant, whereas the original part is RoHS non-compliant. This makes the substitute suitable for applications with RoHS compliance requirements.

Q: Are the packaging options different?

A: The original part is supplied in standard packaging, while the substitute is available in bulk packaging. Both formats contain the same connector specification.

Q: What is the current inventory status?

A: The substitute part DF11-32DS-2DSA(06) has 4794 pieces in stock, providing reliable availability for production requirements.
