MDF7-16P-2.54DSA(01) Equivalent & Substitute Parts
Part Overview
The MDF7-16P-2.54DSA(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting applications. This 16-position vertical header operates at 0.100" (2.54mm) pitch and supports 3A current at 250V. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility across pitch, position count, contact type, and voltage/current ratings while accommodating variations in contact finish, insulation material, and overall dimensions.

Engineering Selection Recommendations
Primary Substitute - Same Manufacturer (Recommended for Direct Replacement):
MDF7-16P-2.54DSA(96) from Hirose Electric Co Ltd is the direct equivalent. This part maintains identical electrical and mechanical specifications to the obsolete MDF7-16P-2.54DSA(01), with the primary difference being active product status and packaging format (Bag vs. unspecified). Both parts are RoHS Compliant with identical operating temperature ranges, current ratings, and voltage specifications. This substitution requires no design modification.
Secondary Substitutes - Cross-Manufacturer Options:
For applications requiring RoHS compliance and active product status, 929700-01-16-RK (3M) and 929705-01-16-EU or 929705-01-16-I (3M) are suitable alternatives. These 3M parts maintain the critical 0.100" (2.54mm) pitch, 16-position, single-row configuration with through-hole solder termination. The 929700-01-16-RK variant offers RoHS Compliant status with Tin contact finish, while 929705 variants provide RoHS Compliant status with Gold contact finish. All 3M options support extended operating temperature range (-40°C ~ 105°C) exceeding the original specification. Current rating of 2.5A is within acceptable tolerance for most applications, though designs requiring the full 3A specification should be evaluated.
Alternative for Non-RoHS Applications:
0022303163 (Molex KK254 series) and 929700-01-16 (3M) provide active product status without RoHS compliance. The Molex part features Tin contact finish and kinked pin termination, offering robust mechanical retention. The 3M 929700-01-16 provides Tin-Lead contact finish with extended temperature range.
Not Recommended:
68024-116 (Amphenol ICC BERGSTIK® II) and 342-90-116-00-592000 (Mill-Max) are RoHS non-compliant and not suitable for new designs requiring regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can MDF7-16P-2.54DSA(96) be used as a direct replacement for MDF7-16P-2.54DSA(01)?
A: Yes. Both parts are manufactured by Hirose Electric Co Ltd with identical electrical and mechanical specifications. The primary difference is product status (Active vs. Obsolete) and packaging format. No design modification is required.
Q: What is the significance of the 2.5A current rating on 3M substitutes versus the 3A rating of the original?
A: The 2.5A rating on 3M parts is lower than the original 3A specification. Applications operating at or near 3A continuous current should be evaluated for thermal margin. For most general-purpose applications operating below 2.5A, this difference is not critical.
Q: Are there differences in contact finish between substitute options?
A: Yes. The original MDF7-16P-2.54DSA(01) features Gold contact finish (30.0µin thickness). Substitutes offer Gold, Tin, or Tin-Lead finishes. Gold finishes provide superior corrosion resistance and lower contact resistance. Tin and Tin-Lead finishes are acceptable for standard applications but may exhibit higher contact resistance in low-signal applications.
Q: Which substitute is best for RoHS-compliant designs?
A: MDF7-16P-2.54DSA(96) (Hirose) is the primary choice, maintaining identical specifications with RoHS Compliant status. For cross-manufacturer options, 929700-01-16-RK, 929705-01-16-EU, and 929705-01-16-I (all 3M) are RoHS Compliant alternatives.
Q: Do packaging format differences affect electrical performance?
A: No. Packaging format (Bag, Bulk, Tube) affects logistics and handling only. Electrical and mechanical performance is identical regardless of packaging.
Q: What is the impact of extended operating temperature range on substitute selection?
A: 3M substitutes support -40°C ~ 105°C versus the original -35°C ~ 85°C. This extended range provides additional thermal margin for applications in extreme environments. For standard industrial applications within -35°C ~ 85°C, this difference is not critical.
Q: Can 929700-01-16 and 929700-01-16-RK be used interchangeably?
A: Both are 3M 929700 series 16-position headers with identical mechanical configuration. The primary difference is RoHS compliance status (929700-01-16 is non-compliant; 929700-01-16-RK is compliant) and contact finish (Tin-Lead vs. Tin). For new designs, 929700-01-16-RK is preferred.
Q: Are there mechanical compatibility concerns with longer post lengths on some substitutes?
A: Contact Length - Post varies across substitutes (ranging from 0.110" to 0.710"). Longer posts increase overall stacking height. PCB design must accommodate the selected substitute's physical dimensions. Verify clearance to adjacent components before final selection.
