Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Contact finish - mating (Gold)
• Insulation material category (Polyamide/Nylon)
• Current rating (3A)
• Voltage rating (250V)
• Material flammability rating (UL94 V-0)
• RoHS compliance (ROHS3 Compliant)

Allowable Variation Parameters:

• Contact length - mating (within mechanical tolerance)
• Insulation height (within mechanical tolerance)
• Insulation material grade (PA6T vs PA9T within polyamide family)
• Operating temperature range (provided minimum and maximum are met or exceeded)
• Product status (active preferred for discontinued parts)
• Additional features (Pick and Place capability)

The Würth Elektronik 61232420621 qualifies as a substitute based on matching all mandatory parameters while exhibiting minor allowable variations in contact length, insulation height, and insulation material grade.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 61232420621 is the manufacturer-recommended substitute for the discontinued 61202420621. Both components maintain ROHS3 compliance and UL94 V-0 flammability certification, ensuring regulatory continuity in applications requiring these standards.

The substitute part is currently in active production status, providing superior long-term availability and supply chain stability compared to the discontinued main part. The 61232420621 incorporates Pick and Place capability, which enhances manufacturing efficiency in high-volume production environments.

The contact length difference (0.232" vs 0.200") and insulation height variation (0.358" vs 0.365") fall within standard mechanical tolerances for this connector family and do not affect electrical performance or mating compatibility. The insulation material upgrade from PA6T to PA9T represents an improvement in thermal and mechanical properties within the polyamide family.

The operating temperature range of the substitute (-40°C ~ 105°C) is suitable for applications operating within this envelope. Applications requiring operation above 105°C must evaluate the temperature limitation against specific design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 61232420621 directly replace the 61202420621 in existing designs?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, shrouding, termination method, and fastening mechanism. The mechanical variations in contact length and insulation height are within standard tolerances for this connector family and do not affect mating compatibility or electrical performance.

Q: What is the significance of the insulation material change from PA6T to PA9T?

A: PA9T (Nylon 9T) offers improved thermal stability and mechanical properties compared to PA6T (Nylon 6T). This represents a material enhancement within the polyamide family and does not affect compatibility or electrical characteristics.

Q: Does the operating temperature range difference affect substitution suitability?

A: The substitute part operates from -40°C to 105°C, compared to the main part's -40°C to 125°C range. For applications requiring sustained operation above 105°C, the temperature limitation must be evaluated against specific design requirements. For applications within the -40°C to 105°C envelope, the substitute is fully suitable.

Q: What does "Pick and Place" capability mean for the substitute part?

A: Pick and Place capability indicates the connector is optimized for automated assembly processes, improving manufacturing efficiency and consistency in high-volume production environments. This feature does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 61202420621 and 61232420621 are ROHS3 compliant and carry UL94 V-0 flammability certification, ensuring regulatory compliance for applications requiring these standards.

Q: What is the current availability status of each part?

A: The 61202420621 is discontinued at DiGi Electronics with 934 pieces available from existing inventory. The 61232420621 is in active production with 680 pieces currently in stock, providing superior long-term procurement stability.
