TML 15512 Equivalent & Substitute Parts

Part Overview

The TML 15512 is an enclosed AC/DC converter manufactured by Traco Power, designed for commercial ITE (Information Technology Equipment) applications. This 15W multi-output converter provides 5V at 2A, with dual auxiliary outputs at ±12V (200mA each), operating from universal AC/DC input ranges of 90–264 VAC or 85–370 VDC.

The TML 15512 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this converter is currently deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TML 15512 are identified based on the following criteria:

Primary Substitution Parameters:

• Identical or compatible output voltage configuration (5V primary output with ±12V auxiliary outputs)
• Matching or higher power capacity (15W or greater)
• Compatible input voltage range (universal AC/DC input)
• Through-hole mounting compatibility
• Enclosed module package type
• ROHS3 compliance and regulatory certifications (CE, cURus minimum)
• Same or compatible DIP module footprint class

Substitution Logic: Two substitute parts meet these criteria. The TML 20512 offers increased power capacity (20W) with enhanced specifications while maintaining the same output voltage structure and footprint class. The TMP 15512 provides equivalent power rating (15W) with identical output configuration but represents an alternative series within the Traco Power product line, offering active product status and extended temperature range.

Parameter Comparison

Engineering Selection Recommendations

TML 20512 Selection Criteria: The TML 20512 is recommended for applications requiring increased power capacity beyond 15W. This substitute maintains active product status, ensuring long-term availability and supply chain stability. It provides enhanced specifications including higher output current capacity (2.8A on the 5V rail versus 2A), improved efficiency (84% versus 80%), and extended operating temperature range (−25°C to 70°C). The TML 20512 carries expanded regulatory certifications (CB, CE, cURus) and maintains 8-DIP module compatibility. Physical dimensions are slightly reduced, which may benefit space-constrained designs. This substitute is suitable for new designs or legacy system upgrades where power margin is beneficial.

TMP 15512 Selection Criteria: The TMP 15512 is recommended for direct replacement applications requiring identical power rating (15W) and output current specifications. This substitute offers active product status and the most comprehensive regulatory certifications (CB, CE, cULus, cURus). The extended operating temperature range (−25°C to 70°C) provides thermal margin over the obsolete TML 15512. However, the TMP 15512 uses a 7-DIP module package with 5 leads, differing from the 8-DIP footprint of the main part. PCB layout modification is required for this substitution. The TMP 15512 is suitable for legacy system maintenance where footprint redesign is acceptable and regulatory compliance enhancement is desired.

Compliance Considerations: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental regulatory posture of the TML 15512. Selection between substitutes should prioritize application power requirements, available PCB space, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the TML 20512 directly replace the TML 15512 without PCB modification?

A: The TML 20512 maintains 8-DIP module compatibility with the TML 15512, enabling direct pin-for-pin substitution. However, physical dimensions differ slightly (69.5mm × 47.5mm × 21.7mm versus 74.0mm × 54.0mm × 22.0mm). Verify mounting hole spacing and clearance in your specific PCB layout before substitution.

Q: What are the key differences between the TML 20512 and TMP 15512 substitutes?

A: The TML 20512 provides 20W power capacity with 2.8A on the 5V output, while the TMP 15512 matches the original 15W rating with 2A on the 5V output. The TML 20512 uses an 8-DIP module; the TMP 15512 uses a 7-DIP module with 5 leads, requiring PCB redesign. The TMP 15512 offers superior regulatory certifications (includes cULus) and lower efficiency (74% versus 84%).

Q: Is the TML 15512 still available for purchase?

A: The TML 15512 is classified as obsolete. While inventory may exist in distribution channels, long-term availability is not guaranteed. Substitution with active-status alternatives (TML 20512 or TMP 15512) is recommended for new procurements and system redesigns.

Q: What is the impact of the different DIP module packages on substitution?

A: The TML 15512 and TML 20512 both use 8-DIP modules, allowing direct PCB footprint compatibility. The TMP 15512 uses a 7-DIP module with 5 leads, requiring PCB layout modification including new mounting holes and trace routing. Verify lead count and pinout compatibility before selecting the TMP 15512.

Q: Are the output voltage specifications identical across all three converters?

A: The TML 15512 specifies only the 5V primary output in the provided data. Both substitutes (TML 20512 and TMP 15512) explicitly provide 5V, 12V, and −12V outputs. Confirm that your application utilizes or can accommodate the ±12V auxiliary outputs before substitution.

Q: Which substitute is recommended for thermal-constrained applications?

A: Both the TML 20512 and TMP 15512 support extended operating temperature range (−25°C to 70°C) compared to the TML 15512 (−25°C to 60°C). The TML 20512 offers superior efficiency (84%), generating less heat during operation. For thermally constrained designs, the TML 20512 is the preferred substitute.

Q: Do all three converters meet the same regulatory standards?

A: The TML 15512 carries CE and cURus certifications. The TML 20512 adds CB certification. The TMP 15512 provides the most comprehensive certifications: CB, CE, cULus, and cURus. For applications requiring specific regulatory approvals, verify that the selected substitute meets all required standards.
