Key Parameters

Substitute Part Grouping Explanation

The DF3E-8P-2V(54) qualifies as a direct substitute for the DF3E-8P-2V(50) based on the following critical parameters:

• Connector Type & Contact Configuration: Both are 8-position male pin headers with identical pitch (2.00mm)
• Electrical Ratings: Both support 250VAC operation with identical operating temperature range (-55°C ~ 105°C)
• Mechanical Compatibility: Both feature surface mount termination, push-pull fastening, and shrouded 4-wall design
• Material & Compliance: Both use brass contacts with gold plating, polyamide insulation, and UL94 V-0 flammability rating
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The substitution is valid across all specified electrical and mechanical parameters. Differences in product status, packaging format, and insulation color do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-8P-2V(54) is the qualified substitute for the obsolete DF3E-8P-2V(50). Selection is based on:

• Functional Equivalence: All electrical and mechanical parameters match across connector type, contact configuration, pitch, voltage rating, temperature range, and termination method.
• Compliance Alignment: Both parts meet UL94 V-0 flammability requirements and carry identical MSL ratings.
• Product Status: The DF3E-8P-2V(54) is classified as Last Time Buy, providing a defined procurement window before full discontinuation. The DF3E-8P-2V(50) is obsolete and should not be specified for new designs.
• Inventory Availability: The substitute part maintains adequate stock levels (900 Pcs) for production requirements.

Frequently Asked Questions (FAQ)

Q: Can DF3E-8P-2V(54) be used as a direct replacement for DF3E-8P-2V(50)?

A: Yes. Both parts are functionally equivalent across all critical electrical and mechanical parameters, including connector type, contact configuration, pitch, voltage rating, operating temperature, and termination method. The parts are interchangeable at the circuit board level.

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

A: The primary differences are product status and packaging. The DF3E-8P-2V(50) is obsolete, while the DF3E-8P-2V(54) is Last Time Buy. The substitute is supplied in tube packaging versus unspecified packaging for the original. Insulation color differs (black versus beige), but this is a cosmetic distinction with no functional impact.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both parts share identical mechanical dimensions, pitch, mounting type (surface mount), and shrouding configuration. PCB footprints and assembly processes remain unchanged.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Should I transition to DF3E-8P-2V(54) for new designs?

A: Yes. The DF3E-8P-2V(50) is obsolete and should not be specified for new designs. The DF3E-8P-2V(54) is the current equivalent and should be used for all new applications and design revisions.
