F5E2 Infrared Emitter 880nm Equivalent & Substitute Parts

Part Overview

The F5E2 is an infrared emitter manufactured by onsemi, designed for 880nm wavelength applications requiring 100mA forward current in a TO-46-2 metal can package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. Substitute parts maintain core electrical compatibility while offering active product status and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitute parts for the F5E2 are qualified based on the following allowed parameters:

Maximum DC forward current: 100mA (exact match required)
Package / Case: TO-46-2 metal can (mechanical compatibility)
Mounting type: Through hole (board-level compatibility)
Operating temperature range: -65°C ~ 125°C (thermal envelope match)
Moisture sensitivity level: 1 (Unlimited) (handling compatibility)

The substitute parts listed operate at 935nm wavelength instead of 880nm. This wavelength shift is within the near-infrared spectrum and represents a standard alternative in IR emitter product lines. All substitutes maintain identical current ratings, package form factors, and thermal operating ranges as the F5E2.

Engineering Selection Recommendations

All three substitute parts (OP130, OP130W, OP133W) are active products manufactured by TT Electronics/Optek Technology with ROHS3 compliance certification. The F5E2 carries no documented RoHS status, whereas all substitutes meet current environmental compliance requirements.

Selection among substitutes depends on application-specific viewing angle and radiant intensity requirements:

OP130 provides the narrowest viewing angle (18°) with 1mW/cm² radiant intensity, suitable for focused beam applications.
OP130W offers a 50° viewing angle with 1mW/cm² radiant intensity, providing moderate beam spread.
OP133W delivers the highest radiant intensity (5mW/cm² @ 100mA) at 50° viewing angle, appropriate for applications requiring maximum optical output.

All substitutes maintain electrical compatibility with the F5E2 through identical 100mA current rating and compatible forward voltage (1.75V vs. 1.7V). The wavelength shift from 880nm to 935nm represents a standard product line transition and must be evaluated against specific system detector sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can OP130, OP130W, and OP133W be used as direct replacements for F5E2?

A: Electrical and mechanical compatibility is maintained through identical 100mA current ratings, TO-46-2 package form factors, and through-hole mounting. However, the wavelength difference (880nm to 935nm) requires system-level evaluation. Applications with wavelength-specific detector requirements must confirm compatibility before substitution.

Q: What are the key differences between OP130, OP130W, and OP133W?

A: The three parts differ in viewing angle and radiant intensity. OP130 features an 18° viewing angle with 1mW/cm² intensity. OP130W provides a 50° viewing angle with 1mW/cm² intensity. OP133W offers the same 50° viewing angle but with higher radiant intensity of 5mW/cm² @ 100mA. Package construction also differs: OP130 uses a lens top metal can, while OP130W and OP133W use standard metal cans.

Q: Are all substitute parts RoHS compliant?

A: Yes. OP130, OP130W, and OP133W are all ROHS3 compliant. The original F5E2 carries no documented RoHS certification status.

Q: Do the substitute parts operate within the same temperature range as F5E2?

A: Yes. All substitute parts maintain the identical operating temperature range of -65°C ~ 125°C (TA), ensuring thermal compatibility in equivalent system environments.

Q: What forward voltage should be expected when substituting these parts?

A: The F5E2 specifies 1.7V typical forward voltage. All substitute parts specify 1.75V typical forward voltage. This 0.05V difference is within standard circuit design tolerances for IR emitter applications and does not require circuit redesign.

Q: Are moisture sensitivity levels equivalent across all parts?

A: Yes. The F5E2 and all three substitute parts carry MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.
