Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395210013 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 13 positions at 0.197" (5.00mm) spacing (non-negotiable for PCB footprint compatibility)
• Header Configuration: Male pins with dual-side shrouding in vertical orientation
• Mounting & Termination: Through-hole solder termination
• Electrical Ratings: Voltage and current ratings must meet or exceed UL specifications (300 V, 15 A minimum)
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating required
• Physical Dimensions: Contact tail length and insulation height within acceptable tolerance ranges for PCB assembly

The Phoenix Contact 1753657 qualifies as a manufacturer-recommended substitute based on matching all critical mechanical and electrical parameters within specified tolerances.

Engineering Selection Recommendations

Primary Part – Molex 0395210013: Select when original design specifications require the Eurostyle ESE 39521 series designation, when UL current rating of 15 A is mandatory, or when supply from Molex is preferred. Active product status ensures continued availability and support.

Substitute Part – Phoenix Contact 1753657: Select as an equivalent when supply constraints affect Molex availability. This part meets all critical mechanical and electrical compatibility requirements. The Phoenix Contact COMBICON MSTBV series provides IEC electrical ratings (12 A / 400 V) in addition to UL ratings, offering broader international compliance documentation. The minor differences in contact tail length (0.154" vs. 0.150") and insulation height (0.472" vs. 0.470") fall within standard PCB assembly tolerances and do not affect functional performance. Both parts carry identical RoHS3 compliance, UL94 V-0 flammability rating, and moisture sensitivity classification.

Current Rating Consideration: The Phoenix Contact substitute is rated at 12 A (UL) compared to the Molex 15 A rating. Applications requiring the full 15 A capacity must retain the Molex part. Applications operating below 12 A can safely use the Phoenix Contact substitute without derating.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753657 be used as a direct drop-in replacement for the Molex 0395210013?

A: Yes, for applications operating at or below 12 A. The Phoenix Contact part matches all critical mechanical parameters (13 positions, 5.00mm pitch, vertical orientation, through-hole solder termination) and electrical specifications (300 V UL rating, UL94 V-0 flammability). Physical dimensions (contact tail length and insulation height) are within standard PCB assembly tolerances. If your circuit requires the full 15 A capacity of the Molex part, the substitute is not appropriate.

Q: Are there any PCB footprint compatibility issues between these parts?

A: No. Both parts share identical position count (13), pitch spacing (5.00mm), and mounting type (through-hole). The minor dimensional variations in contact tail length (0.004" difference) and insulation height (0.002" difference) are within standard manufacturing tolerances and do not affect PCB layout or assembly processes.

Q: What is the difference between UL and IEC electrical ratings?

A: UL ratings apply to North American electrical standards and safety certifications. IEC ratings apply to international standards. The Phoenix Contact 1753657 provides both UL ratings (12 A / 300 V) and IEC ratings (12 A / 400 V), offering broader compliance documentation for global applications. The Molex 0395210013 specifies UL ratings only (15 A / 300 V).

Q: Does the lower current rating of the Phoenix Contact part affect reliability?

A: No, provided your application operates within the 12 A limit. Both parts carry identical UL94 V-0 flammability certification and moisture sensitivity classification (MSL 1). The current rating difference reflects design specifications, not reliability or quality differences. Operating below the rated current ensures safe, reliable performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the Molex 0395210013 and Phoenix Contact 1753657 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications for export and tariff purposes.

Q: What is the operating temperature range for the Phoenix Contact part?

A: The Phoenix Contact 1753657 does not specify an operating temperature range in the provided technical data. The Molex 0395210013 specifies -40°C to 105°C. For applications requiring confirmed temperature specifications, contact Phoenix Contact directly or consult the complete datasheet.

Q: Can I mix Molex and Phoenix Contact parts in the same assembly?

A: Yes. Both parts are mechanically and electrically compatible and can coexist in the same circuit board assembly without functional issues. However, for consistency and simplified inventory management, using a single manufacturer per design is recommended.
