Substitute Part Grouping Explanation

The substitute part 61234020621 qualifies as a direct equivalent based on the following critical parameters:

• Identical connector type, contact type, and pitch (2.54mm)
• Matching position count (40) and row configuration (2 rows)
• Identical row spacing, shrouding style, and termination method
• Equivalent electrical ratings (3A current, 250V voltage)
• Matching operating temperature range (-40°C ~ 125°C)
• Identical material compliance (UL94 V-0, ROHS3, MSL 1)
• Same series designation (WR-BHD)

Minor dimensional variations in contact length (0.200" vs 0.197") and insulation height (0.365" vs 0.362") fall within acceptable tolerances for this connector category and do not affect functional compatibility. The substitute part is currently active in production with established inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 61234020621 is the direct substitute for the discontinued 61204020621. Both parts maintain identical electrical and mechanical specifications within the WR-BHD series. The substitute part carries active product status with higher inventory availability (2071 units vs 643 units), ensuring supply chain continuity.

Both parts satisfy identical compliance requirements: ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. The substitute part includes Pick and Place feature designation, indicating optimized manufacturing compatibility for automated assembly processes.

The minor dimensional tolerances between contact length and insulation height are within standard manufacturing specifications for this connector category and do not impact functional performance or mating compatibility.

Frequently Asked Questions (FAQ)

Q: Are parts 61204020621 and 61234020621 mechanically interchangeable?

A: Yes. Both parts feature identical pitch (2.54mm), position count (40), row configuration (2 rows), shrouding style (4-wall), and termination method (solder). Minor dimensional variations in contact length (0.003" difference) and insulation height (0.003" difference) are within acceptable manufacturing tolerances and do not affect mating or functional performance.

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

A: The primary difference is product status. Part 61204020621 is discontinued at DiGi Electronics, while 61234020621 is active in production. The substitute includes Pick and Place feature designation and is available in Cut Tape packaging. Electrical and mechanical specifications remain equivalent.

Q: Can I use 61234020621 as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical electrical ratings (3A, 250V), operating temperature range (-40°C ~ 125°C), and compliance certifications (ROHS3, UL94 V-0). No design modifications are required.

Q: What does the Cut Tape packaging mean for 61234020621?

A: Cut Tape (CT) packaging indicates the parts are supplied on tape that is cut to specific lengths, optimized for automated pick-and-place assembly equipment. This differs from bulk or reel packaging and provides better handling for high-volume manufacturing processes.

Q: Are both parts RoHS compliant?

A: Yes. Both 61204020621 and 61234020621 are ROHS3 compliant and carry identical material flammability ratings (UL94 V-0) and moisture sensitivity levels (MSL 1 - Unlimited).
