DPC-10-120B1 Equivalent & Substitute Parts

Part Overview

The DPC-10-120B1 is a laminated core power transformer manufactured by Pulse Electronics, rated at 1.2VA with dual primary and secondary windings. This through-hole mounted component is designed for PC pin termination and supports both 115V and 230V primary inputs with configurable secondary outputs (parallel 5V or series 10V). The part is currently active in production with 1183 units in stock. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align within acceptable tolerances for direct board-level replacement.

Substitute Part Grouping Explanation

The DPC-10-120 from Signal Transformer qualifies as a direct substitute based on the following alignment criteria:

Electrical Parameters: Identical primary voltage inputs (115V, 230V), secondary voltage configurations (parallel 5V, series 10V), output current ratings (parallel 240mA, series 120mA), power rating (1.2VA), winding configuration (dual primary, dual secondary), and isolation voltage (1500Vrms).

Mechanical Parameters: Dimensions are within acceptable tolerance (length 34.90mm vs. 34.93mm, width 28.60mm vs. 28.58mm, height 30.15mm vs. 30.18mm). Mounting type (through hole) and termination style (PC pin) are identical.

Compliance & Status: Both parts maintain active product status, RoHS compliance, REACH unaffected designation, and identical ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the DPC-10-120B1 and DPC-10-120 maintain active product status and meet regulatory compliance requirements. The DPC-10-120B1 carries RoHS Compliant certification with MSL Level 1 (unlimited moisture sensitivity), while the DPC-10-120 carries ROHS3 Compliant certification. Dimensional tolerances between the two parts are negligible (maximum variance 0.03mm in length and width, 0.03mm in height), ensuring mechanical compatibility in through-hole PCB applications. Both parts share identical electrical specifications, core construction, winding configuration, and isolation ratings. Selection between these parts should be based on supply chain availability, packaging requirements (DPC-10-120B1 available in standard packaging; DPC-10-120 available in bulk), and specific RoHS certification requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can DPC-10-120 replace DPC-10-120B1 in existing designs? A: Yes. Both transformers provide identical electrical performance across all specified parameters including voltage ratings, current capacity, and isolation voltage. Mechanical dimensions are within acceptable tolerance for through-hole PCB mounting.

Q: What are the key differences between these parts? A: The primary differences are manufacturer (Pulse Electronics vs. Signal Transformer), packaging format (standard vs. bulk), RoHS certification level (RoHS Compliant vs. ROHS3 Compliant), and MSL rating (Level 1 vs. Not Applicable). Electrical and mechanical specifications are equivalent.

Q: Are there any dimensional concerns for PCB layout? A: No. Maximum dimensional variance is 0.03mm across length, width, and height measurements. Both parts are rated for identical through-hole mounting with PC pin termination and will fit existing footprints without modification.

Q: Do both parts meet the same compliance standards? A: Both parts are REACH Unaffected and carry EAR99 ECCN classification with identical HTSUS codes. RoHS compliance differs in certification level (RoHS Compliant vs. ROHS3 Compliant), which should be verified against specific application requirements.

Q: What is the inventory status for each part? A: DPC-10-120B1 has 1183 units in stock. DPC-10-120 has 1570 units in stock. Both are active products with current availability.
