RLD60P030XF Equivalent & Substitute Parts

Part Overview

The RLD60P030XF is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., rated for 60V maximum voltage with a 300 mA hold current. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part features a through-hole radial disc package with cURus and TUV approval certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Substitutes (60V Rating): Parts 60R030XPR and 60R030XU maintain identical electrical specifications to the RLD60P030XF, including 60V maximum voltage, 300 mA hold current, 600 mA trip current, and matching resistance characteristics. Both are active products with improved RoHS3 compliance status.

Secondary Substitutes (72V Rating): Parts 72R030XPR and RXEF030-AP operate at 72V maximum voltage, exceeding the original 60V specification. These parts are electrically compatible in 60V applications due to their higher voltage rating and identical current and resistance parameters. The 72R030XPR is a Littelfuse POLY-FUSE® product, while RXEF030-AP is a Littelfuse PolySwitch® variant with expanded approval certifications (CQC, CSA, TUV, UL).

Cross-Manufacturer Substitute (60V Rating): MF-R030 is a Bourns Inc. Multifuse® product rated for 60V with 300 mA hold current. It matches the primary electrical specifications with a slightly lower initial resistance (760 mOhms vs. 880 mOhms minimum) and marginally higher seated height (0.528" vs. 0.512" maximum).

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): 60R030XPR and 60R030XU are the primary substitutes for RLD60P030XF. Both maintain identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. Selection between these two depends on packaging requirements: 60R030XPR is supplied in Cut Tape format, while 60R030XU is supplied in Bulk.

Higher Voltage Alternative: 72R030XPR and RXEF030-AP are suitable for applications where the circuit design permits operation at 72V. Both parts maintain identical current and resistance characteristics. RXEF030-AP provides expanded approval certifications (CQC, CSA, TUV, UL) compared to 72R030XPR (cURus, TUV).

Cross-Manufacturer Option: MF-R030 from Bourns Inc. is functionally equivalent for 60V applications. The lower initial resistance specification (760 mOhms minimum vs. 880 mOhms) represents a minor deviation that does not affect substitution eligibility. All mechanical dimensions and lead spacing remain compatible.

Frequently Asked Questions (FAQ)

Q: Can 60R030XPR directly replace RLD60P030XF? A: Yes. Both parts share identical voltage (60V), current (300 mA hold, 600 mA trip), resistance, and operating temperature specifications. The primary difference is product status: RLD60P030XF is obsolete while 60R030XPR is active with ROHS3 compliance.

Q: What is the difference between 60R030XPR and 60R030XU? A: Both parts are electrically and mechanically identical. The difference is packaging: 60R030XPR is supplied in Cut Tape (CT) format, while 60R030XU is supplied in Bulk. Selection depends on assembly process requirements.

Q: Can I use 72R030XPR or RXEF030-AP in a 60V circuit? A: Yes. Both parts are rated for 72V maximum voltage, which exceeds the 60V requirement. All electrical parameters (current, resistance, temperature range) are identical to the 60V variants. The higher voltage rating provides additional safety margin.

Q: How does MF-R030 differ from the Littelfuse substitutes? A: MF-R030 is manufactured by Bourns Inc. and has a lower initial resistance specification (760 mOhms minimum vs. 880 mOhms). All other parameters—voltage, current, trip characteristics, and operating temperature—are identical. Mechanical dimensions and lead spacing are compatible.

Q: What certifications apply to each substitute? A: 60R030XPR, 60R030XU, 72R030XPR, and MF-R030 carry cURus and TUV certifications. RXEF030-AP carries CQC, CSA, TUV, and UL certifications, providing the broadest approval coverage.

Q: Is RoHS compliance a factor in selecting a substitute? A: Yes. RLD60P030XF is RoHS non-compliant. All active substitutes (60R030XPR, 60R030XU, 72R030XPR, RXEF030-AP, MF-R030) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.
