Engineering Selection Recommendations
Primary Recommendation: MDF7-16P-2.54DSA(95)
The MDF7-16P-2.54DSA(95) is the direct Hirose equivalent with active product status. It maintains identical electrical and mechanical specifications to the obsolete MDF7-16P-2.54DSA(55), including 16-position, 2.54mm pitch, male pin configuration, tin contact finish, 3A current rating, and UL94 V-0 flammability rating. This part carries ROHS3 compliance and is currently in stock with 1473 units available.
Secondary Recommendations for Cross-Manufacturer Substitution:
351-80-116-00-004101 (Preci-Dip) and 890-80-016-10-003101 (Preci-Dip) are active alternatives with tin contact finish, 3A current rating, ROHS3 compliance, and extended operating temperature range (-55°C ~ 125°C). These parts meet all critical electrical parameters and are suitable for applications requiring enhanced thermal performance.
351-10-116-00-004101 (Preci-Dip) and 890-18-016-10-003101 (Preci-Dip) offer gold contact finish for improved corrosion resistance, with identical electrical ratings and ROHS3 compliance.
Not Recommended for Direct Substitution:
0022303163 (Molex), 342-90-116-00-592000 (Mill-Max), 68024-116 (Amphenol ICC), and 929700-01-16 (3M) lack complete electrical specification data or carry RoHS non-compliance status, limiting their suitability for applications requiring full parameter verification and regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can MDF7-16P-2.54DSA(95) directly replace MDF7-16P-2.54DSA(55)?
A: Yes. Both parts are Hirose MDF7 series headers with identical 16-position, 2.54mm pitch configuration, male pin contacts, tin finish, 3A current rating, and UL94 V-0 flammability rating. The primary difference is product status: MDF7-16P-2.54DSA(55) is obsolete while MDF7-16P-2.54DSA(95) is active with ROHS3 compliance.
Q: What are the key differences between tin-finish and gold-finish alternatives?
A: Tin-finish parts (MDF7-16P-2.54DSA(95), 351-80-116-00-004101, 890-80-016-10-003101) provide standard corrosion resistance and cost efficiency. Gold-finish parts (351-10-116-00-004101, 890-18-016-10-003101) offer enhanced corrosion resistance and improved contact reliability in demanding environments, with identical electrical ratings.
Q: Are there voltage rating differences between substitutes?
A: The original MDF7-16P-2.54DSA(55) is rated 250V. Preci-Dip alternatives (351 and 890 series) are rated 150VDC. For applications requiring 250V operation, MDF7-16P-2.54DSA(95) is the appropriate choice. For applications operating at or below 150VDC, Preci-Dip alternatives are suitable.
Q: What is the significance of operating temperature range differences?
A: MDF7-16P-2.54DSA(55) operates -35°C ~ 85°C. Preci-Dip alternatives extend this to -55°C ~ 125°C, providing broader thermal compatibility. Selection depends on application thermal requirements.
Q: Which substitutes carry current RoHS compliance?
A: MDF7-16P-2.54DSA(95), 0022303163 (Molex), 351-10-116-00-004101, 351-80-116-00-004101, 890-18-016-10-003101, 890-70-016-10-003101, and 890-80-016-10-003101 all carry ROHS3 compliance. Parts from Mill-Max, Amphenol ICC, and 3M are RoHS non-compliant.
Q: What packaging formats are available?
A: MDF7-16P-2.54DSA(95) is supplied in bag packaging. Molex 0022303163 is supplied in bulk. Preci-Dip alternatives (351 and 890 series) are supplied in bulk. Mill-Max 342-90-116-00-592000 is supplied in tube. Amphenol ICC 68024-116 is supplied in bulk. 3M 929700-01-16 is supplied in bulk.
