• Voltage Rating - AC: 475V (exact match or higher required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match or wider range acceptable)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Size / Dimension: 1.220" L x 0.354" W (31.00mm x 9.00mm) (exact match required)
• Height - Seated (Max): 0.689" (17.50mm) (exact match required)
• Lead Spacing: 1.043" (26.50mm) (exact match required)
• Termination: PC Pins (exact match required)

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must satisfy all electrical, mechanical, and compliance criteria to ensure direct interchangeability without circuit redesign or PCB modification.

Parameter Comparison

Engineering Selection Recommendations

DPPM12S1K-F is the direct substitute for DPPM12S1K. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications across all critical parameters.

Key Differentiation:

The DPPM12S1K-F carries an Active product status, whereas the DPPM12S1K is classified as Obsolete. This distinction is significant for long-term supply chain planning and component availability.

The DPPM12S1K-F achieves ROHS3 compliance, while the DPPM12S1K is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the DPPM12S1K-F is the appropriate selection.

Both parts maintain identical electrical performance, mechanical fit, and environmental ratings. Selection between these parts should be based on product lifecycle requirements and regulatory compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can DPPM12S1K-F be used as a direct replacement for DPPM12S1K in existing designs?

A: Yes. The DPPM12S1K-F is electrically and mechanically equivalent to DPPM12S1K.
