73F-250-32 Quick Connect Female Crimp Connector Equivalent & Substitute Parts

Part Overview

The 73F-250-32 is a 0.250" (6.35mm) Quick Connect Female Crimp Connector manufactured by 3M, designed for 10-12 AWG wire termination. This non-insulated terminal operates as a free-hanging in-line connector with butted seam construction. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent parts are identified when they maintain identical electrical and mechanical specifications across critical connection parameters, enabling direct substitution in applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 73F-250-32 is determined by strict equivalence across the following critical parameters: tab width (0.250"), tab thickness (0.032"), wire gauge range (10-12 AWG), gender (Female), termination method (Crimp), contact material (Brass), and contact finish (Tin). The D10-250-L from Panduit Corp qualifies as a direct substitute because it maintains all these core electrical and mechanical specifications. Variations in overall length (73F-250-32: 0.630" vs. D10-250-L: 0.660"), mounting features (butted seam vs. serrated termination), and series designation do not affect functional compatibility in applications where the connector interfaces with standard 0.250" quick-connect receptacles.

Parameter Comparison

Engineering Selection Recommendations

Both the 73F-250-32 and D10-250-L are active production components with full regulatory compliance. The 73F-250-32 carries RoHS Compliant status with MSL 1 rating, while the D10-250-L is ROHS3 Compliant with Not Applicable MSL designation. Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8536.90.4000. Selection between these parts should be based on supply chain availability, inventory levels, and specific application environmental requirements. The D10-250-L currently maintains higher inventory availability (1721 pcs vs. 667 pcs), making it a viable alternative when 73F-250-32 stock is constrained.

Frequently Asked Questions (FAQ)

Q: Can the D10-250-L directly replace the 73F-250-32 in existing applications? A: Yes. Both connectors share identical tab width, tab thickness, wire gauge range, gender, termination method, contact material, and contact finish. The 0.030" overall length difference does not affect electrical or mechanical compatibility with standard 0.250" quick-connect receptacles.

Q: What is the significance of the butted seam versus serrated termination feature? A: These are manufacturing construction variations that do not affect the core electrical performance or mechanical interface. Both designs provide secure crimp termination for 10-12 AWG wire.

Q: Are there any compliance differences between these parts? A: Both parts are RoHS compliant and REACH unaffected. The 73F-250-32 specifies RoHS Compliant status with MSL 1, while the D10-250-L specifies ROHS3 Compliant with Not Applicable MSL. Both meet current regulatory requirements for electronic component use.

Q: Does the series designation (3M base product 73F vs. Panduit Pan-Term®) affect substitution? A: No. Series designation reflects manufacturer product line organization and does not impact electrical or mechanical compatibility. Substitution is determined solely by the specified connector parameters.

Q: What packaging format is available for both parts? A: Both the 73F-250-32 and D10-250-L are supplied in Bulk packaging, suitable for high-volume assembly operations.
