RLD60P010XF Equivalent & Substitute Parts

Part Overview

The RLD60P010XF is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., part of the POLY-FUSE® RLD60 series. This through-hole radial disc component is rated for 60V maximum voltage with a 100 mA hold current and 200 mA trip current. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this electrical specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RLD60P010XF is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Voltage - Max: 60V
• Current - Hold (Ih) (Max): 100 mA
• Current - Trip (It): 200 mA
• Current - Max: 40 A
• Time to Trip: 4 s
• Resistance - Initial (Ri) (Min): 2.5 Ohms
• Resistance - Post Trip (R1) (Max): 7.5 Ohms
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Through Hole
• Package / Case: Radial, Disc

Mechanical Compatibility:

• Size / Dimension: 0.291" Dia x 0.122" T (7.40mm x 3.10mm)
• Lead Spacing: 0.201" (5.10mm)

All substitute parts listed below meet these electrical and mechanical parameters. Variations in packaging format (Bulk, Cut Tape, Tape & Box) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse POLY-FUSE® Series (60R010XU, 60R010XPR): These parts are direct Littelfuse equivalents with identical electrical and mechanical specifications to the obsolete RLD60P010XF. Both are ROHS3 compliant and carry cURus approval. The 60R010XU is available in bulk packaging with the highest inventory (6400 pcs), while 60R010XPR is available in cut tape format (3400 pcs). Both are active products suitable for new designs and legacy system support.

Littelfuse PolySwitch® RXEF010-AP: This active Littelfuse product meets all electrical parameters with minor mechanical variation in thickness (0.118" vs 0.122") and lead spacing (0.199" vs 0.201"). It carries expanded approval certifications (CQC, CSA, TUV, UL) and ROHS3 compliance. Available in cut tape packaging (720 pcs). The minimal dimensional difference does not affect electrical performance or PCB compatibility in standard through-hole applications.

Bourns Multifuse® Series (MF-R010, MF-R010-AP, MF-R010-AP-17): All three Bourns variants are parametric equivalents with identical electrical specifications and mechanical dimensions to the RLD60P010XF. All are ROHS3 compliant and active products. MF-R010 offers the highest inventory (17180 pcs) in bulk format. MF-R010-AP is available in cut tape (6721 pcs). MF-R010-AP-17 includes AEC-Q200 automotive qualification and carries the broadest approval certifications (cUL, cURus, TUV, UL), available in tape & box format (1027 pcs).

For new designs requiring automotive qualification, MF-R010-AP-17 is the appropriate selection. For general industrial applications, 60R010XU or MF-R010 provide maximum inventory availability. All listed substitutes are electrically and mechanically compatible with the obsolete RLD60P010XF.

Frequently Asked Questions (FAQ)

Q: Can RXEF010-AP be used as a direct replacement for RLD60P010XF despite the thickness difference?

A: Yes. The RXEF010-AP thickness of 0.118" (3.00mm) versus the RLD60P010XF thickness of 0.122" (3.10mm) represents a 0.04mm difference. This variation does not affect electrical performance or standard through-hole PCB mounting. All electrical parameters—voltage, current, resistance, and trip characteristics—are identical.

Q: What is the difference between Littelfuse and Bourns substitute options?

A: Both manufacturers provide parametrically equivalent parts meeting all electrical and mechanical specifications. Littelfuse options (60R010XU, 60R010XPR, RXEF010-AP) maintain the original manufacturer lineage. Bourns options (MF-R010, MF-R010-AP, MF-R010-AP-17) are cross-manufacturer equivalents. Selection depends on supply chain preference, inventory availability, and required certifications. All are ROHS3 compliant and active products.

Q: Which substitute part should be selected for automotive applications?

A: MF-R010-AP-17 is the only substitute carrying AEC-Q200 automotive qualification. This part is suitable for automotive-grade reliability requirements and includes the broadest approval certifications (cUL, cURus, TUV, UL).

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. Packaging format (Bulk, Cut Tape, Tape & Box) is a supply and handling consideration only. All substitute parts with identical part numbers across different packaging formats have identical electrical and mechanical specifications. Selection should be based on procurement volume and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original RLD60P010XF is RoHS non-compliant, making ROHS3-compliant substitutes necessary for new designs subject to RoHS regulations.

Q: What inventory levels are available for each substitute?

A: 60R010XU (Bulk): 6400 pcs; MF-R010 (Bulk): 17180 pcs; MF-R010-AP (Cut Tape): 6721 pcs; 60R010XPR (Cut Tape): 3400 pcs; MF-R010-AP-17 (Tape & Box): 1027 pcs; RXEF010-AP (Cut Tape): 720 pcs. Inventory levels determine lead time and availability for production requirements.
