Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B02B-WPJES-3 (LF)(SN) is determined by strict equivalence across the following critical parameters:

• Connector Series & Type: WPJ series header with male pin contact type
• Electrical Specifications: 7A current rating and 300V voltage rating
• Mechanical Configuration: 2-position, 5mm pitch, through-hole mounting, shrouded 4-wall design
• Termination & Fastening: Solder termination with latch holder fastening
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, waterproof ingress protection
• Operating Range: -25°C to 85°C temperature specification

The B02B-WPJSS-1 meets all these criteria and represents the active production equivalent within the WPJ series.

Parameter Comparison

Engineering Selection Recommendations

The B02B-WPJSS-1 is the direct functional equivalent of the B02B-WPJES-3 (LF)(SN). Both parts share identical electrical ratings, mechanical dimensions, and environmental certifications. The primary distinction is product status: the B02B-WPJSS-1 is in active production, whereas the B02B-WPJES-3 (LF)(SN) is obsolete.

For new designs or ongoing procurement, the B02B-WPJSS-1 is the appropriate selection. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. The insulation color difference (blue versus natural) is a cosmetic variation that does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the B02B-WPJSS-1 be used as a direct replacement for the B02B-WPJES-3 (LF)(SN)?

A: Yes. Both parts are WPJ series headers with identical electrical ratings (7A, 300V), mechanical configuration (2-position, 5mm pitch, through-hole, shrouded 4-wall), and environmental specifications. The B02B-WPJSS-1 is the active production equivalent.

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

A: The B02B-WPJSS-1 is the current production version of the WPJ series 2-position header. The B02B-WPJES-3 (LF)(SN) is classified as obsolete. Insulation color differs (natural versus blue), but this is a cosmetic distinction without functional impact.

Q: Are there any compatibility concerns when substituting the B02B-WPJSS-1 for the B02B-WPJES-3 (LF)(SN)?

A: No compatibility concerns exist. Both parts conform to identical pitch, position count, mounting type, and electrical specifications. PCB layouts and mating connector requirements remain unchanged.

Q: What packaging is available for the B02B-WPJSS-1?

A: The B02B-WPJSS-1 is supplied in bulk packaging, with 19,627 pieces currently in stock.

Q: Are both parts RoHS compliant?

A: Yes. Both the B02B-WPJES-3 (LF)(SN) and B02B-WPJSS-1 are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 (unlimited) moisture sensitivity level.
