DP241-5-10A21 Equivalent & Substitute Parts

Part Overview

The DP241-5-10A21 is a laminated core power transformer manufactured by Pulse Electronics, rated for 12VA with dual primary windings (115V/230V) and a single secondary winding (10V, 1.2A max output). This chassis-mount transformer features a center tap and solder/quick connect termination options. The part is currently active in production with 701 units in stock and maintains full ROHS3 compliance.

Equivalent and substitute parts are identified when component availability changes, supply chain disruptions occur, or design flexibility permits functional alternatives within specified electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

The Hammond Manufacturing 186C10 qualifies as a functional substitute for the DP241-5-10A21 based on the following matched electrical and mechanical parameters:

• Identical power rating: 12VA
• Identical primary voltage configuration: 115V, 230V (dual windings)
• Identical secondary voltage: 10V
• Identical secondary current capacity: 1.2A maximum output
• Identical core type: Laminated
• Identical center tap configuration: Yes
• Identical mounting type: Chassis Mount
• Identical termination style: Solder, Quick Connect
• Both parts maintain ROHS3 compliance and REACH Unaffected status

Substitution is valid when these core electrical specifications and mounting characteristics are required by the application circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both the DP241-5-10A21 and 186C10 are active production components with ROHS3 compliance and REACH Unaffected status, making either suitable for new designs or component replacement scenarios.

The DP241-5-10A21 provides 2500Vrms isolation voltage, which exceeds the 186C10 specification of 2000Vrms. Selection should be based on the isolation voltage requirement of the target application circuit.

The 186C10 exhibits slightly larger physical dimensions (width: 43.82mm vs. 41.40mm; height: 41.15mm vs. 35.05mm). PCB layout and enclosure space constraints must be evaluated before substitution.

Both parts are available in production quantities and maintain identical electrical performance for the specified 12VA, 10V secondary output application.

Frequently Asked Questions (FAQ)

Q: Can the 186C10 replace the DP241-5-10A21 in existing designs?

A: Substitution is electrically valid when the application requires 12VA power, 115V/230V primary input, 10V secondary output at 1.2A maximum, and center-tap configuration. Physical space constraints must be verified due to dimensional differences (width +2.42mm, height +6.10mm).

Q: What is the isolation voltage difference, and does it matter?

A: The DP241-5-10A21 specifies 2500Vrms isolation while the 186C10 specifies 2000Vrms. If the application circuit design requires 2500Vrms isolation, the DP241-5-10A21 must be used. If 2000Vrms isolation is sufficient, either part is acceptable.

Q: Are both parts RoHS compliant?

A: Yes. Both the DP241-5-10A21 and 186C10 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What are the packaging differences?

A: The DP241-5-10A21 is packaged in standard format, while the 186C10 is packaged in a Box. Both use identical solder and quick connect termination styles.

Q: Do the parts have the same mounting footprint?

A: Both are chassis-mount transformers with identical length (71.37mm). Width and height differ slightly: the 186C10 is 2.42mm wider and 6.10mm taller. PCB layout and mechanical clearance must be confirmed before substitution.
