PM-15-15 Equivalent & Substitute Parts

Part Overview

The PM-15-15 is an enclosed AC/DC converter manufactured by MEAN WELL USA Inc., rated for 15V output at 1A with 15W power capacity. This unit accepts universal input voltage ranging from 85–264 VAC or 120–370 VDC and is designed for medical applications. The PM-15-15 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where this model is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM-15-15 are qualified based on the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Output voltage: 15V
• Output current capacity: 1A minimum
• Power rating: 15W
• Package type: 4-DIP Module
• Mounting type: Through Hole
• Input voltage compatibility: Universal input (85–264 VAC minimum)
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1 (Unlimited)

Acceptable Variations:

• Input voltage range may extend beyond the original specification (e.g., 80–264 VAC is acceptable as it encompasses the 85–264 VAC requirement)
• Operating temperature range may be wider than the original
• Efficiency and regulation specifications may differ
• Physical dimensions may vary within the 4-DIP Module envelope
• Approval agencies and certifications may differ based on application region

The two substitute parts identified—MPM-15-15 and ECL15US15-E—satisfy all mandatory parameters while offering improved performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

MPM-15-15 (MEAN WELL USA Inc.)

The MPM-15-15 is the primary substitute for the obsolete PM-15-15. Both units originate from the same manufacturer, ensuring design continuity and compatibility with existing PCB layouts and mechanical assemblies. The MPM-15-15 maintains the same electrical output specifications (15V, 1A, 15W) and 4-DIP Module package format. The substitute offers superior performance with 87% efficiency compared to 79% in the original, improved line regulation (±0.3% versus ±0.5%), and an extended operating temperature range (−40°C to +85°C). The MPM-15-15 carries active product status with higher inventory availability (1137 units in stock). Approval certifications include CB, CE, cURus, EAC, and TUV. The input voltage range of 80–264 VAC encompasses the original 85–264 VAC specification. This unit is suitable for direct replacement in medical and household appliance applications.

ECL15US15-E (XP Power)

The ECL15US15-E provides an alternative substitute from XP Power, maintaining identical electrical output specifications and 4-DIP Module packaging. This unit matches the original input voltage range (85–264 VAC) and operating temperature specification (−20°C to +70°C). The ECL15US15-E carries active product status with 872 units in stock. Approval certifications include CSA, cUL, EN, IEC, and UL, with compliance to standard 62368-1. The efficiency rating of 80% is marginally higher than the original PM-15-15. This substitute is appropriate for applications requiring XP Power product qualification or where specific regional certifications (CSA, cUL) are mandated. Physical dimensions differ slightly from the original (65.0mm × 33.3mm × 24.4mm versus 75.0mm × 53.0mm × 22.7mm), requiring verification of mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can the MPM-15-15 be used as a direct replacement for the PM-15-15 in existing designs?

A: Yes. Both units share identical electrical output specifications (15V, 1A, 15W), the same 4-DIP Module package type, and through-hole mounting configuration. The MPM-15-15 is manufactured by the same company (MEAN WELL USA Inc.) and is designed as a successor to the obsolete PM-15-15. Existing PCB layouts and mechanical assemblies require no modification.

Q: What are the key differences between the MPM-15-15 and ECL15US15-E substitutes?

A: Both substitutes meet the core electrical requirements of the PM-15-15. The MPM-15-15 offers superior efficiency (87% versus 80%) and improved regulation specifications. The ECL15US15-E provides alternative certification pathways (CSA, cUL, EN, IEC, UL versus CB, CE, cURus, EAC, TUV) and may be preferred in applications requiring specific regional approvals. Physical dimensions differ between the two units; the ECL15US15-E is more compact.

Q: Are there input voltage compatibility concerns when substituting the PM-15-15?

A: No. The PM-15-15 accepts 85–264 VAC input. The MPM-15-15 accepts 80–264 VAC, which encompasses the original range. The ECL15US15-E accepts 85–264 VAC, matching the original specification exactly. Both substitutes are fully compatible with the original input voltage requirements.

Q: Does the PM-15-15 support DC input, and do the substitutes?

A: The PM-15-15 specification includes 120–370 VDC input capability. The MPM-15-15 and ECL15US15-E specifications provided list only VAC input ranges. If DC input is required for the application, the original PM-15-15 specification must be verified against the substitute datasheets before selection.

Q: What is the physical size difference between the PM-15-15 and its substitutes?

A: The PM-15-15 measures 75.0mm × 53.0mm × 22.7mm. The MPM-15-15 measures 52.4mm × 27.2mm × 24.0mm (more compact). The ECL15US15-E measures 65.0mm × 33.3mm × 24.4mm (intermediate size). All three units use the 4-DIP Module package format. Mechanical fit within the target application enclosure must be verified before final selection.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both the MPM-15-15 and ECL15US15-E carry ROHS3 Compliant status, matching the original PM-15-15 specification.

Q: Which substitute offers the widest operating temperature range?

A: The MPM-15-15 operates from −40°C to +85°C, providing the widest temperature range. The PM-15-15 and ECL15US15-E both operate from −20°C to +70°C. Selection depends on the thermal environment of the target application.

Q: What is the inventory status of each part?

A: The PM-15-15 (obsolete) has 777 units in stock. The MPM-15-15 (active) has 1137 units in stock. The ECL15US15-E (active) has 872 units in stock. Both active substitutes offer higher availability than the obsolete original.
