HPR407C Equivalent & Substitute Parts

Part Overview

The HPR407C is an isolated module DC-DC converter manufactured by Murata Power Solutions Inc., designed for ITE (Commercial) applications. This component provides a single 12V output with 62mA maximum current capacity from a 10.8V to 13.2V input range, delivering 750mW of power. The HPR407C operates across an extended temperature range of -40°C to 100°C with 3kV isolation and 77% efficiency.

The HPR407C is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HPR407C is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 10.8V to 13.2V (must match or encompass)
• Output voltage: 12V (must be identical)
• Isolation voltage: 3kV (must be equal or greater)
• Output current capacity: must equal or exceed 62mA
• Single output configuration requirement

Mechanical Compatibility Criteria:

• Mounting type: Through Hole (must match)
• Package form factor: 7-SIP Module (must be compatible with PCB layout)
• Physical dimensions: 0.77" L x 0.24" W x 0.40" H (must fit within design envelope)

Regulatory and Compliance Criteria:

• RoHS3 compliance (required for equivalent parts)
• REACH compliance status (must be unaffected or compliant)

The MEV1S1212SC meets all substitution criteria. It maintains identical input/output voltage specifications, exceeds the output current requirement (84mA vs. 62mA), provides equivalent isolation voltage, and shares the same through-hole 7-SIP module form factor with identical physical dimensions. Both parts are manufactured by Murata Power Solutions Inc. and carry ROHS3 and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

The MEV1S1212SC is the direct substitute for the HPR407C based on the following engineering criteria:

Electrical Performance: The MEV1S1212SC maintains identical input voltage range (10.8V to 13.2V) and output voltage (12V) specifications. The increased output current capacity (84mA versus 62mA) and higher power rating (1W versus 750mW) provide design margin without introducing incompatibility. The isolation voltage remains at 3kV, meeting the original specification.

Mechanical Compatibility: Both components share identical physical dimensions (0.77" L x 0.24" W x 0.40" H) and through-hole mounting type. The MEV1S1212SC uses a 7-SIP Module with 5 leads compared to the HPR407C's 4-lead configuration. This difference does not prevent substitution, as the additional lead accommodates the higher power rating while maintaining PCB footprint compatibility for standard through-hole mounting.

Regulatory Compliance: Both parts carry ROHS3 compliance and REACH Unaffected status, satisfying current regulatory requirements for ITE (Commercial) applications.

Product Availability: The MEV1S1212SC holds active product status with 12,400 units in stock, ensuring supply chain continuity compared to the obsolete HPR407C.

Temperature Consideration: The MEV1S1212SC operates across -40°C to 85°C, compared to the HPR407C's -40°C to 100°C range. Applications requiring operation above 85°C must evaluate thermal management or alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the MEV1S1212SC directly replace the HPR407C in existing designs?

A: Yes, the MEV1S1212SC is a direct substitute for the HPR407C. Both components share identical input/output voltage specifications, isolation voltage, physical dimensions, and through-hole mounting type. The MEV1S1212SC provides higher output current capacity (84mA versus 62mA) and improved efficiency (88% versus 77%), making it functionally superior within the same form factor.

Q: What is the significance of the 5-lead versus 4-lead package difference?

A: The MEV1S1212SC uses a 7-SIP Module with 5 leads, while the HPR407C uses 4 leads. The additional lead accommodates the higher power rating of the MEV1S1212SC (1W versus 750mW). Both components maintain identical physical dimensions and through-hole mounting compatibility. PCB designs using standard through-hole footprints for the HPR407C can accommodate the MEV1S1212SC without layout modifications.

Q: Are there temperature range limitations when substituting the MEV1S1212SC?

A: The MEV1S1212SC operates across -40°C to 85°C, while the HPR407C operates to 100°C. Applications requiring sustained operation above 85°C must evaluate whether the MEV1S1212SC's upper temperature limit is acceptable for the specific thermal environment. For applications within the -40°C to 85°C range, the MEV1S1212SC is fully compatible.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the HPR407C and MEV1S1212SC are ROHS3 compliant and REACH Unaffected, satisfying current regulatory requirements for ITE (Commercial) applications.

Q: Why is the HPR407C classified as obsolete?

A: The HPR407C is obsolete due to its lower power rating (750mW) and reduced output current capacity (62mA). The MEV1S1212SC represents the current generation of Murata's isolated DC-DC converter line, offering improved performance characteristics (1W power rating, 84mA output current, 88% efficiency) within the same form factor and compliance framework.

Q: What is the inventory status of the substitute part?

A: The MEV1S1212SC is in active production with 12,400 units currently in stock, ensuring reliable supply chain availability for new designs and legacy system support.
